Just out of curiosity, couldn't bochs' x87 fpu implementation be of some use
here?
It is approx 12k of C code and it is LGPL. Supposedly it is not fast but
conformant.
Or does it need to be (re-)implemented in Pascal itself?
(Not implying it would be easy anyway, but still)
Note that FPC needs LGPL + static linking exception (the softfloat units are in
the RTL).
Nikolai might be right, looking at it’s license it seems usable:
https://github.com/lubomyr/bochs/blob/master/cpu/fpu/fsincos.cc
Same as the softfloat code we use it seems.
I started a first translation and committed it to
